 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an outer wall 1 constructed in a heat insulating structure, and FIG. 3 shows an attachment 3 of a heat insulating exterior material 2 used when the heat insulating outer wall 1 is constructed.

The heat insulating outer wall 1 is constructed by stacking concrete formwork blocks 4 with joint mortar as required, and appropriately arranging vertical streaks 5 and horizontal streaks 6 and driving them into a formwork 7 The heat-insulating exterior material 2 is attached to one side of the casting form 7, and concrete 8 is placed in the space of the form block 4. As shown in FIG. 4, through-holes 10 are preliminarily formed in the shell 9 on the exterior material mounting side of the mold blocks 4 forming the driving mold 7 at predetermined intervals.

The exterior material mounting member 3 forms a screw hole a for screwing a bolt in the center of the rectangular plate 11 made of metal, which is offset in one of the longitudinal directions of the rectangular plate 11 in the width direction. Two locking members 12 are provided on both sides of the plate body 11 in the width direction.

More specifically, the plate 11 has a length in the longitudinal direction of about 3 times the diameter of the through hole 10 and a width in the width direction is slightly wider than the diameter of the through hole 10. It is narrow and can be inserted into the through hole 10 formed in the shell 9 from one side surface thereof, and by changing the posture after the through hole 10 is inserted, both sides in the longitudinal direction thereof can be changed. Is formed in a shape to be locked around the through hole 10 on the other side of the shell 9. On the other hand, the locking member 12 is made of a plastic material such as wire and has a length about twice that of the plate body 11. One end side in the longitudinal direction of the locking member 12 is specified to identify the specified portion. Are welded to the plate body 11 on both sides in the width direction on the side opposite to the offset side of the screw hole a.

The procedure of attaching the heat insulating exterior material 2 to one side of the driving mold 7 using the exterior material attaching tool 3 having such a configuration will be described. As shown in FIG. Standing on one side surface of the shell 9 with the other end side thereof, the plate body 11 of the shell 9 is inserted into the through holes 10 formed in the predetermined mold block 4 of the driving mold 7. Then, as shown by phantom lines in the figure, the upper end of the plate body 11 is locked to the other side surface of the shell 9 and the locking member 12 is pulled, and both sides in the longitudinal direction of the plate body 11 are connected to the shell 9 and the like. It is locked around the through hole 10 on the side surface.

Next, as shown in FIG. 6, the locking member 12 is bent downward so that the locking member 12 is locked to one side surface of the shell 9. The fixing and fixing of the mounting tool 3 to the driving form 7 is completed by means of this, and under the locking and fixing of the mounting tool 3 to this mold 7, the screw hole a formed in the plate 11 is It is important to set the dimensions so as to face the predetermined position of the through hole 10. Also, with the locking member 12 bent and the mounting tool 3 locked and fixed to the frame 7, the mounting is performed. It is also important in terms of stabilizing the posture of the attachment 3 that the center of gravity of the attachment 3 is located below the point of engagement with the through hole 10 of the engagement member 12.

In this way, the fixture 3 is locked and fixed in the through hole 10 of the predetermined mold block 4, and as shown in FIGS. 1 and 2, for example, as shown in FIGS. A sandwiched heat insulating exterior material 2 is prepared between two refractory boards 14 such as reinforced gypsum boards, and screw holes a of each plate body 11 fixed to the frame 7 are fixed to the exterior material 2. A plate body 11 is formed in which a bolt insertion hole b that is concentric with is formed, and an exterior material fixing bolt 15 is inserted into the bolt insertion hole b so that the bolt 15 faces the through hole 10. It is screwed into the screw hole a.

With the above, the attachment of the heat insulating exterior material 2 to the one side surface of the driving form 7 is completed. According to such means, the attachment with high strength can be surely made as compared with the case of using the adhesive means. In comparison with the case of using the bolt driving means, the exterior material 2 can be attached before the concrete 8 is placed in the space of the form block 4, which is excellent in workability. Since the construction period can be shortened, the exterior material 2 can be efficiently attached to the driving form 7.

7 and 8 show another embodiment of the fixture 3. This one is characterized in that the locking member 12 is one and the mounting tool 3 has a simple structure, and also has a springback function so that the mounting tool 3 can be mounted on the driving form 7. Yes

That is, the attachment 3 is formed by bending both sides of the plate body 11 in the longitudinal direction into one side surface to form the plate body 11 in a mountain shape, and biasing the plate body 11 to one side in the longitudinal direction thereof. And a screw hole c for inserting a bolt and a hole d for inserting a locking member are respectively formed in the center in the width direction and are coaxial with the screw hole c for inserting a bolt. While welding the nut 16 with a lock, the locking member 12 is inserted into the hole d, the locking member 12 is bent along the plate body 11, and one of the locking members 12 is bent. The portion is welded to the other side surface of the plate body 11.

According to such a configuration, the plate body 11 is inserted into the through hole 10 and the upper end portion of the plate body 11 is inserted into the shell 9 in the same manner as the mounting procedure of the mounting tool 3 of the embodiment. The locking member 12 is pulled by being locked to the side surface, and the locking members 12 are bent downward with the bent ends on both sides in the longitudinal direction of the plate body 11 being locked to the other side surface of the shell 9. The locking member 12 is locked and fixed to one side surface of the shell 9, and when the locking member 12 is bent and locked to the one side surface of the shell 9, the plate body 11 is bent in a both-end locking state. By doing so, the attachment 3 can be firmly locked and fixed to the mold 7 by the spring back force of the plate 11.

Although the plate body 11 is made of metal in each of the above-described embodiments, it may be changed to a synthetic resin body, and the locking member 12 can be attached to the plate body 11. Can be glued or otherwise mechanically secured. Further, as the mounting object of the exterior material 2, the driving mold 7 in which the mold block 4 is raised is shown, but in addition, for example, the driving mold made of half precast concrete and the wooden mold are made to face each other, and in between. It goes without saying that the above-mentioned driving form, etc. when constructing the outer wall 1 by pouring concrete into the outer wall 1 can be the target of attachment of the exterior material according to the present invention, and in this case also, the above-mentioned form block is used. Even when targeting a driving mold, it is desirable to form the through holes 10 in the mold in advance, but it is also possible to carry out the procedure of forming the through holes 10 when attaching the exterior material.
